The Supereal SR9900 is a versatile 10/100M Ethernet controller that combines several essential components to deliver robust network connectivity. This controller includes an IEEE 802.3u compliant Media Access Controller (MAC), a USB bus controller, and embedded memory. It also incorporates a linear regulator (LDO) for cost-effective design.

Thanks to advanced DSP technology and mixed-mode signal technology, the SR9900 ensures high-speed data transmission over CAT 5 UTP cables or CAT 3 UTP cables (limited to 10Mbps). It employs various functions such as Crossover Detection, Auto-Correction, polarity correction, adaptive equalization, and more to ensure reliable data transmission and reception.

The SR9900 includes embedded One-Time-Programmable (OTP) memory and supports Advanced Configuration Power Management Interface (ACPI) for efficient power management in modern operating systems. It also enables remote wake-up functionality, supporting AMD Magic Packet and Microsoft Wake-Up Frame, while preventing unwanted wake-up events.

Furthermore, the SR9900 is fully compliant with Microsoft NDIS5, NDIS6, and IEEE 802 standards, offering checksum features, IP Layer 2 priority encoding, and VLAN support. These features reduce CPU utilization, making it ideal for network servers.

The controller supports Protocol offload, which offloads common protocols to the NIC hardware to minimize power consumption and prevent spurious wake-up. It complies with IEEE 802.3az (Energy Efficient Ethernet), operating in Low Power Idle mode during low link utilization to conserve power.

Additionally, the SR9900 leverages USB 2.0 technology, providing higher bandwidth and improved protocols for efficient data exchange between the host and device. Its aggressive power management feature allows selective suspend to save energy.

In summary, the Supereal SR9900 Ethernet controller is a versatile and power-efficient solution suitable for a wide range of applications, including desktops, mobile devices, workstations, servers, communication platforms, docking stations, and embedded systems. Its advanced features ensure reliable and energy-efficient network connectivity across various market segments and emerging applications.
